Results
The details of the 18 cases are summarized in Fig.6.
In our series,
the median age was 58 years (range 6–74 years),
and there were 7 women and 11 men.
The most common symptom was neck pain,
presented in seven patients.
Back pain was presented in five patients.
Four patients presented lower extremity weakness.
Less common symptoms were lower extremity paresthesias (three patients),
upper extremity weakness (two patients),
and shoulder pain (only one case).
Prior to the diagnosis,
there were no patients with history of trauma and in five cases (28%) there was a history of spinal surgery.
Only one patient associated congenital malformations.
The most frequently affected level was T5 (39%) and in second place T4 with six cases (33%).
T6,
T7,
T8 levels were affected in four patients each.
Less common was the involvement of T3,
T9 (three patients each) and T10 (one patient).
Ten patients (55%) demonstrated only increased T2WI cord signal adjacent to the level of dorsal indentation and syringomyelia was demonstrated in two of them.
Alterations in CSF flow were demonstrated in all patients being high or moderate in more than half of the cases. In nine patients (50%) the webs were directly visible on T2 TRUE FISP dynamic sequences.
